NEW METAMATERIALS. “At this moment, making negative-refractive index material in the microwave regime is quite feasible. It would be a big challenge to make such materials in the optical frequency range, although there have been some amazing advances in some US and European laboratories that may help realize our design in — say — the next three to five years.”
